GRAIN-BINDER.

' SPEGTFIGATION vforming; part of Letters Patent No. 684,869, dated October 22, 1901.

Application filed June 3, 1901.

To all whom/ it Hetty concern: l

Be it known thatI, RICHARD M. RoGnRs,of Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Grain-Binders; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this speciiication.

This invention is an improvement in grainbinders, and has particular reference to the needle actuating and bundle compressing mechanisms; and its object is to simplify the construction of such parts by utilizing the needleas the prime means for actuating the compressor and by providing for a very quick return of the needle after the compressing and tying operations.

The invention consists in theimproved 'constructions and combinations of parts hereinafter claimed, and the accompanying draw ings illustrate only so much of the bundletying mechanisms of a grain-binder as is necessary to impart a clear understanding of the invention to those skilled in the manufacture of such machines, and in said drawings- Figure 1 is a side elevation showing positions of parts during the compression of a bundle. Fig. 2 is a similar view with parts in position for ejecting bundle. Figs. 3 and 4 are detail sectional views on lines 3 3 and 4 4, respectively, of Fig. 2.

A designates the needle of the machine, inounted on a shaft B just below the bindingtable C, said shaft having a crank-arm b connected by an actuating-pitman D to a wheel E above the table, said parts being of the ordinary construction and arrangement, with the exception that the pitman D instead of being connected to a xed crank-pin on wheel E is connected to a movable crank-pin d, which works in an arc-shaped slot ein the wheel, said slot extending about one-third around the wheel. The object of this peculiar construction is to allow the needle to be retracted very suddenly and to remain at rest during part of the time of collecting a bundle and until pin d is picked up at the rear end of the slot and. carried around with the wheel until it passes beyond the center of gravity at the top side of the wheel after the bundle is com- Serial No. 62,990. (No model.)

pressed and tied, when the needle can drop Y back quickly, pin d sliding to the front end.v

of the slot at this time, and then the needle In rear of or below the needle is a rotatable compressor-spider having four arms f, which are preferably curved so that theuppermost arm will project above the table through a suitable slot therein in line with the needle and toward the upper end of the table or toward the needle when the latter is raised. This compressor is journaledv on a bolt g, attached to a suitable support G, and is so located that the ends of its arms will pass close to the heel of the needle as the compressor rotates. A bolt H is secured in a housing I at the side of support G and is' adapted to be projected into the path of the spider-arms, so as to engage the latter by means of a spring hwithin the housing. This bolt stops the rotation of the spider when its uppermost arm is in a verticalposition by engaging the next' arm of the spider, as shown. On the heel of the needle is a lug a, which when the needle is raised engages the adjoining horizontal arm of the spider and forces the latter to partially rotate, so that the upper arm thereof moves toward the needle, compressing the bundle of grain caught between the needle and upper arm of the spider, as shownin Fig, l. On the heel of the needle, beside lu g a, is a cam-ange l a,which will engage and force back bolt I-I (see Figs. 3 and Ll) before lug o; engages the arm f, and this iiange will hold back thebolt during the compression of a bundle (see Fig. l) and until the needle drops back, releasing the arm of the spider, which passes the bolt H before cam a releases it. The outward and downward movement of the tied bundle in escaping from the tying mechanism gives a quarter-turn to the spider, which is arrested, however, by the engagement of the nextspidewarmf with the bolt, the bundle meanwhile having beenmoved clear of the spider-compressor by the bundle-ejector arm J on the shaft of wheel E, (see Fig. 2,) as usual. T

It will be observed that the bundle is pressed during the rise of the needle and by the action of the needle, which is directly operated from the wheel E, and the compression com spider is operated by the cam-lug a. on heel of needle, which constructiongreatly simplities the mechanism, and the'quick return or drop of the needle, owing to the slot-and-pin connection between pitman and wheel, is also quite advantageous.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

1. In a bundle-tying mechanism for selfbinding machines, the combination of the needle, the actuating-wheel having an arc-shaped slot extending partly around it near its periphery, and the pitman for operating the needle from said wheel, said pitman having its end slidingly engaged in the said slot in the wheel to permit quick return or drop of the needle.

2. In a bundle-tying mechanism for selfbinders, the combination of the needle, its shaft, and crank-arm thereon, the actuatingwheel having an arcshaped slot extending `about one-third of its circumference near its periphery, and a pitman having one end pivoted to the crank-arm and the other end connected to a pin loosely engaged in the wheelslot, for the purpose and substantially as described.

3. In abundle tying and compressing mechanism for self-binders, the combination of the needle and its actuating mechanism; with a rotary compressor pivoted beside the needle, and cam-lug connected with the needle adapted to engage and operate the compressor when the needle rises.

Ll. The combination of the needle, a rotary compressor beside the needle having a series of compressing arms, a lug on the needle adapted to engage one arm of the compressor when the needle rises so as to partially rotate the compressor backward or toward the needle, and means for allowing the compressor to rotate sufliciently to discharge Ithe bundle, when the needle drops back.

5. The combination of the needle, and means for reciprocating it; with a rotary compressor pivoted below the table adjacent to the heel of needle, a bolt adapted to lock the compressor during the collection of a bundle, means adapted to actuate the compressor when the needle rises, and means to disengage the bolt momentarily from the compressor to permit the latter to be partly rotated when the needle drops, f'or the purpose and substantially as described. y

6. The combination of the needle, the actuating-wheel, and the pitman for operating the needle from said wheel, said pitman having its end slidingly engaged with a slot in the wheel to" permit quick return or drop of the needle; with a rotary compressor pivoted beside the needle and having a series of arms, and a lug on the needle adapted to engage and operate the compressor when the needle rises,su bstalr tially as described.V

7. The combination of the needle, and means for reciprocating it; with a rotary compressor pivoted below the table adjacent to the heel of needle and having a series of radial arms, a bolt adapted to engage the compressor-arms, a lug on the needle adapted to actuate the compressor when the needle rises, and a cam on the needle adapted to disengage the bolt momentarily from the compresser to permit the latter to be partly rotated when the needle drops, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
